IMPR'VEM ENT IN SYRINGS.

Specification forming part of Letters Patent No. 70,540, dated `November 5,1867.

To all Mmm it may concern? Be a known that I JAMES JESSEX, of

Newport, Newport county, Rhode; Island,

` which will enable those .skilled in the art to make and use the same, reference being had tothe accompanying .-drawings, forming part of this specification. A ,A

Thisv invention relates to a. newand limproved syringe which is applicablefto allpurf poses for which IaI syringe, is required, and which consequently, lterm a universal syringe, t being capableA 0f .being used @S au.

enemata apparatus or .as .a douchefsyringe,

and is portable and capable of lbeing adapted4 for use in a moment of time.

My improved syringe is of the modern class in which, the pump (cylinderiand piston) is dispensed with, and an elasticgbulb usedinT1 stead. .A V.

The invention consists, irst, in a receiver or reservoir provided with a glass or transparent plate, inserted in its .side, so that when the device is used for enema-giving purposes a precise quantity of liquid may be used-to wit, a gill, pint, &c., as may be required; and this receiver or reservoir is designed to accompany the apparatus and form a part of the same.

The invention consists, second, in a rose or perforated nozzle, which I term a douche, whereby wounds may be irrigated with a delicate spray of warm or cold water, as may be required. This device is also valuable for cleansing` or washing the eyes.

The invention consists, third, in using, in connection with an elastic bulb as a suction and force pump, an elastic and a metallic tube, placed at or attached to opposite ends of the bulb, and using in connection therewith an air-chamber, all being arranged as herein fully shown and described, whereby a continuous stream may be thrown from the eduction-tube and the device adjusted to suit the various uses required of it.

The invention consists, fourth, in a novel and improved arrangement of packing, whereby perfectly-tight joints may be obtained.

In theaccompanying sheet of drawings, Figure 1 is a view of my improved apparatus,

tion; Fig. 2, a side. view of A.thesame with the parts differently arranged, but notv in, sec-I, tion 5' Figs. 3, 4, 5,6, 7, 8', and 9, detached,

views of partsy pertaining to theA same.

' Similar' letters of reference indicate .corre'f :spending parts.. p Y i A represents. a receiver or reservoir, which maybe-of metal, (block-tin would be a goodf material provided with a collar or nozzle, 01;, having an'fexternal screw-thread to receive a cap, "b, t hrfough the center of which there isil an openingfor a pipe or tube, B, to pass, the'l latter extending. down to', the bottom of the .l receiver orreservoir, as shown clearly in Fig.; L yIn the side of the receiverl there is itted'. a platev of glass, Ax, or.other.transparent Ina-f j r,teriahand the side of the; receiver .adjoining theatranspa'rent plate is graduated,-sothat anydesired or givenv quantity of iiuid'niaybe placed withinit. This is 'an importantfea-gY ture, as it enables injections to begiveninac.- f; curate quantities, as' a physicianv may pre1., scribe. The sideof .this receiver` er.r eserfvqir1'A extends down below its bottom c, and the sdN below the bottom has a cover, d, fitted over it, forming a box, in which an elastic tube may be placed when not required for use.

The tube B has a female screw, d', cut in its upper end, to receive a small screw, e, of an elastic or metal tube, an elastic tube, O, being shown in Fig. 1, and in Fig. 2 the screw at one end of an elastic bulb, D, is shown. The tube B admitsof the contents of the receiver A being entirely drawn or pumped out of it, the bulb D serving as a PHDP- E is an air-chamber, which causes a continuous stream to be thrown or ejected from the bulb D, and in Fig. 2 this air-chamber is` shown attached to the opposite end of the bulb D, and a ilexible tube connected to the air-chamber. In Fig. l the bulb D is shown lattached at one end to the elastic or flexible tube C, and the air-chamber `attached to the opposite end, with a metallic tube, F, attached to the air-chamber, said tube F having thev attached to F, and the elastic tube C attached to the other end of the bulb.

The connections of these several parts may, be varied at will, according as circumstances may require; but in all casesit is essential that a metallic or rigid part must be connected to one end of the bulb D, and an elastic tube to the opposite end; and in order to render the device applicable to all adjustments which may be required, curved and angular metal elbows E F may be used, as shown in Figs. 8 and 9.

In certain cases, when required, the flexible suction and the metallic discharge may be applied to one and the same end of the elastic bulb, as will be understood by referring to Fig. 1, in which the elastic or iiexible suction is then attached to the air-chamber.

I would remark that valves f are employed (shown in Fig. 1) and applied in the diiferent joints and connections, as may be required. Necessary valves are also employed in the air-chamber.

In order to render the connections or joints perfect, I have the male screw formed with a socket, g, in which the packing is placed, (see Fig. 1,) and this socket receives the end of the tube l1., in which the female screw is cut. This socket prevents the packing from spreading laterally under the pressure, and causes a tight joint or connection; besides, the packing is totally concealed, and the joint or connection has a far neater appearance than when it is exposed, as in the old plan.

Figs. 4 and 5 represent what I term v a douche'which consists oi' a cap or nozzle,

1'., having a perforated plate, j, at its end. This perforated plate causes a ne spray to be ejected from the discharge-tube, and is extremely valuable for irrigating wounds, ulcers, or sores, and for washing the eye.

I would remark that eduction-pipes H H (see Figs. 6 and 7) may be used as circumstances mayrequire, and these pipes attached either to the elastic tube or to the metallic one, whichever is used for the force or eduction.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The employment or use, in connection with a syringe, of a receiver or reservoir, A, provided with a glass or other transparent plate, A", and with a screw-cap, b, and tube B, substantially as and for the purpose set forth.

2. The combination of a metallic and an elastic tube with an elastic bulb, when the former are attached to opposite 'ends of the latter, and used either in connection with or Without an air-chamber, for the purpose specified. i

3. The rose-nozzle or,douche, composed of the cup t' and perforated plate j, when used in connection or combined with a syringe provided withv an elastic bulb, substantially as and for the purpose specified.

4. Providing the male screw of the connections'or joints with a socket, g, to receive the packing, and prevent its lateral expansion under pressure where the two parts of the connection or joint are screwed together.

5. The arrangement of the rigid discharging-pipe and the flexible suction-tube and their valves at one end of the bulb, substantially as herein shown and described.

The above specification of my invention signed by me this 26th day of March, 1867.

JAMES J. ESSEX.
